The Lowdown
Alright folks, Rusty here. Let’s get into what’s coming up for Jaconé over the next couple of weeks.
We’ve got a bit of a slow start, but things really start to cook in the second week. The standout window is going to be from the 26th of July right through into early August, with some serious south swell energy building in. The water temp is sitting about average for the time of year, nothing wild there.
Friday 17th July kicks off with clean, small waves around 3ft from the SE with a light offshore breeze. It’s tidy, but not going to get the heart pumping. That trend of small, clean surf carries through the weekend and into Monday. The Monday 20th July morning session has a little more push at 6ft from the ENE, but the period is short (7 seconds), so it’s a bit lumpy and less organised. Tuesday afternoon sees a small bump back up to 4ft with an 8-second period.
We hit a flat spot mid-week. Wednesday 22nd and Thursday 23rd are pretty weak – Wednesday morning only has 3ft and the combined energy is a measly 89, so you’re really scratching for anything. Friday 24th morning is a bit perkier with 3ft from the S, but the wind turns onshore in the arvo and ruins it.
Now, here’s where it gets good. Saturday 25th July morning at Jaconé is a ripper. Glassy conditions, 5ft of S swell with a 10-second period, and a combined energy of 508. Clean, fun, and a solid option for intermediates. The crowd can turn up here sometimes, but early doors you’ll be sweet.
Sunday 26th July is the real highlight. The morning is glassy again with a punchy 7ft S groundswell, period stretching out to 13 seconds, and the combined energy is a powerful 1631. This is proper, grunty surf for experienced surfers – well-shaped, clean, and long waits between sets. The arvo stays clean but the wind picks up a touch, so get on it early.
Monday 27th July morning holds at 4ft with a solid 11-second period and offshore winds, a nice clean leftover. But the afternoon gets howling with 30 km/h winds, so game over.
Tuesday 28th is small again, then Wednesday 29th is a write-off with strong cross-onshore winds and a messy 4ft swell.
Thursday 30th July morning is a monster. We’re looking at 12ft from the SSW with a 13-second period and a combined energy of 4454. That is huge, and the file says it’s predicted to be too big for this break. This is experts-only territory, and even then, it’s sketchy. The swell direction is a bit off too, so expect a washing machine.
Friday 31st July morning pulls back to a still-chunky 8ft from the SSW, glassy conditions, and a combined energy of 2048. This is still a big, powerful swell, perfect for the crew who know what they’re doing. The period is 11 seconds, so it’s got some punch but the sets are manageable.
Saturday 1st August morning keeps the good run going: glassy, 8ft from the SSE with a 13-second period and a combined energy of 2014. Another excellent option for experienced surfers, clean and with plenty of juice.
So, bottom line: the first week is a slow, clean grind. The standout is undeniably Sunday 26th July morning for the best balance of size, period, and glass. If you’re an expert, the 31st and 1st of August are also absolute crackers. Don’t bother with the 30th unless you’ve got a death wish and a big board.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
